2. Use the Windows Assessment and Development Kit (ADK)
2.1 Download and install SQL Server
- Download Microsoft SQL Server from Microsoft’s website. The ADK will use a SQL Server database to store its entries so you can’t go further without installing this.
- Open the SQL Server installer.
- The installer gives you three options to install SQL Server. The easiest and fastest way is to go with Basic, so choose that.
- Click on accept when you are presented with the license agreement.
- Click on install and wait until the installation is finished.
2.2 Download and install the ADK
- Download the ADK installer here.
- Open the ADK installer. Click on Next twice and agree to the terms of the license agreement.
- Now on the Select the features you want to install window, make sure to select Application Compatibility Tools and deselect everything else because that’s the only tool we’ll be using.
- Wait for the installer to finish.
2.3 Use the ADK to detect compatibility issues and fix them
- Search for Compatibility Administrator in Start and run the application.
- Click on Search in the menu bar and choose Fixed Programs… from the list.
- Click on the Find Now button and wait until the application has finished the search. This goes through the folder where your programs are stored and matches them against the database of a known application list with compatibility issues. In the end, the program will come up with a list of applications in the bottom pane.
- Double click on an item from the list.
- It will take you back to the main section of the program with an entry being selected. Right-click on the selected item and copy it.
- Go through the list until you find an entry titled New Database under Custom Databases.
- Right-click on New Database and paste the copied entry.
- Repeat steps 4-7 for each item on the list.
- Only if you have a 64-bit Windows: In your version of Windows, programs are not only stored in the Program Files folder, but also in the Program Files (x86) folder. That’s why you must also search for compatibility issues in there. Click on Browse in the top right corner and select Program Files (x86) folder or, even easier, just add (x86) before the last dash in the File(s) to search bar. Now repeat steps 3-8 again for this folder.
